High silver-filled content mono-component hybrid resin for die attach. PROTAVIC® ACH 30200 is useful when a high level of thermal and electrical conductivity combined with a good properties of moisture resistance is required.
The PROTAVIC® ACH 30200 epoxy adhesive combines an excellent adhesive properties.
Its good latency enables it to be kept at 20 ± 2°C for 1 week with a little increase of viscosity, so the viscosity remains virtually unchanged throughout the working day. The long pot life ensures that the product remains at a reasonably constant viscosity and facilitate application. Its rheology makes the product useful for an application by dispensing.

METHOD OF USE
- Take the package out of the freezer at not more than 1 hour before use in order to prevent any re-absorption of moisture.
- Work on clean surfaces or clean all surfaces in order to remove any dirt or grease. Do not deposit the adhesive on a substrate which has just been cleaned with chlorinated solvents.
- Apply the adhesive (by dispensing)
- Cure using one of the curing cycles compatible with the components, the substrate and the manufacturing conditions.
